Figure 5.4 All Comparisons Report
Each comparison is the difference in estimated utilities between the chip type labeling the row and the chip type labeling the column. Small p-values are colored with an intense blue or red color, depending on the sign of the difference. For example, based on the blue colors across the Gyro row, you can see that Gyro chips have significantly lower utility than all other chip types. Barbecue chips have higher utility than all other chip types, though they do not differ significantly from Southern Barbecue chips.
Note: Because the All Comparisons Report p-values are not corrected for multiple comparisons, use them as a guide.
